CY2020	us-gaap	Use Of Estimates UseOfEstimates	Use of Estimates — The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the balance sheet dates and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term include the determination of the allowance for credit losses and the determination of any impairment of goodwill or intangible assets. It is reasonably possible Pinnacle Financial's estimate of the allowance for credit losses and determination of impairment of goodwill or intangible assets could change as a result of the continued impact of the COVID-19 pandemic on the economy. The resulting change in these estimates could be material to Pinnacle Financial's consolidated financial statements.

These amendments, among other things, clarify that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting under Topic 323, Investments-Equity Method and Joint Ventures, for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments also clarify that, when determining the accounting for certain forward contracts and purchased options a company should not consider, whether upon settlement or exercise, if the underlying securities would be accounted for under the equity method or fair value option. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early application is permitted, including early adoption in an interim period. An entity should apply ASU 2020-01 prospectively at the beginning of the interim period that includes the adoption date. Pinnacle Financial is assessing ASU 2020-01 and its impact on its accounting and disclosures. </span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes to simplify various aspects of the current guidance to promote consistent application of the standard among reporting entities by moving certain exceptions to the general principles.
